Question

Okay, so I've finally started the next Summer of the Dragon chapter, and I'm tackling mealtimes at Grimmauld Place. I'm using Mrs Beeton for menu ideas (the link is here if anyone thinks it might be useful - it includes suggested menus for each month of the year).

Would the Blacks say grace? If so, would it be in Latin or English? Nothing in canon seems to argue either way, so I'd be interested to hear anyone's opinions.
